Okay i have searched all of the threads and i can not seem to find anything that helps. I cant seem to remove the under drive pulley nut even with a impact! What can i do to get this nut off. I just got a lighter one i want to put on but i cant get the old one off Please help me! Thanks

 

have you tried soaking it down with PB? after you get the nut off, you probobly need an alternator pulley remover tool. You can probobly rent one from AutosuckZone.
